GW4-12 outdoor type series disconnectors

GW4-12 outdoor type series disconnectors
Product Description
GW4 series outdoor disconnectors shall be applied to switching of the HV
transmission equipment with rated frequency 50Hz or 60Hz when no load is
applied to the HV power supply line and electric isolation of the HV electric
equipments, such as the HV bus, the breaker, etc. to be overhauled from the
charged HV circuit.
This series of disconnector is the double-column horizontal rotating central
single-break type disconnector and is composed of the base, the supporting
insulator and the conductive part; and the earthing switches can be added on
one side or two sides. Moreover, the main switch and the earthing switch can be
applied to three-phase linked operation and split-phase operations by using the
electric mechanism or the manual mechanism.
The vertical transmission rod sh , all drive one supporting insulator of 
th , e disconnector to rotate when the operating mechanism of the main
switch runs; and the other supporting insulator shall be driven to rotate by
using one set of intersected four-
bar linkage structure
